I have a Nordyne G5RC080C-16 gas furnace which had the blower fail. It was in A/C mode with the condenser still running but no blowerat the furnace/evap. A tech repakced the blow motor and capacitor -- still no blowe, even in direct 'fan' mode. There is a code (one flash) suggesting limit switch or ?

The heat and cool cycles seem to do their jobs, calling for heat engages the heat circuit, indues engages, gas valve opens, ignightor, but the blower does not come on.

The A/C mode engages the condenser -- frosts back, but again the blower does not come on.

Circuit board problems?
